<p>Recall that the FFTW API is divided into three parts<a name="DOCF6" href="#FOOT6"><sup>6</sup></a>: the <em>basic interface</em>
computes a single transform of contiguous data, the <em>advanced
interface</em> computes transforms of multiple or strided arrays, and the
<em>guru interface</em> supports the most general data layouts,
multiplicities, and strides.  This section describes the the basic
interface, which we expect to satisfy the needs of most users.
